4577370e9b Miscellaneous const changes and utilities
The list of remote refs in struct transport should be const, because
builtin-fetch will get confused if it changes.

The url in git_connect should be const (and work on a copy) instead of
requiring the caller to copy it.

match_refs doesn't modify the refspecs it gets.

get_fetch_map and get_remote_ref don't change the list they get.

Allow transport get_refs_list methods to modify the struct transport.

Add a function to copy a list of refs, when a function needs a mutable
copy of a const list.

Add a function to check the type of a ref, as per the code in connect.c

9ad7c5ae8a git-fetch: do not fail when remote branch disappears
When the branch named with branch.$name.merge is not covered by
the fetch configuration for the remote repository named with
branch.$name.remote, we automatically add that branch to the set
of branches to be fetched.  However, if the remote repository
does not have that branch (e.g. it used to exist, but got
removed), this is not a reason to fail the git-fetch itself.

The situation however will be noticed if git-fetch was called by
git-pull, as the resulting FETCH_HEAD would not have any entry
that is marked for merging.

2467a4fa03 Remove duplicate ref matches in fetch
If multiple refspecs matched the same ref, the update would be
processed multiple times. Now having the same destination for the same
source has no additional effect, and having the same destination for
different sources is an error.

28b91f8ad9 Rename remote.uri to remote.url within remote handling internals
Anyplace we talk about the address of a remote repository we always
refer to it as a URL, especially in the configuration file and
.git/remotes where we call it "remote.$n.url" or start the first
line with "URL:".  Calling this value a uri within the internal C
code just doesn't jive well with our commonly accepted terms.

85682c1903 Correct handling of branch.$name.merge in builtin-fetch
My prior bug fix for git-push titled "Don't configure remote "." to
fetch everything to itself" actually broke t5520 as we were unable
to evaluate a branch configuration of:

  [branch "copy"]
    remote = .
    merge = refs/heads/master

as remote "." did not have a "remote...fetch" configuration entry to
offer up refs/heads/master as a possible candidate available to be
fetched and merged.  In shell script git-fetch and prior to the above
mentioned commit this was hardcoded for a url of "." to be the set of
local branches.

Chasing down this bug led me to the conclusion that our prior behavior
with regards to branch.$name.merge was incorrect.  In the shell script
based git-fetch implementation we only fetched and merged a branch if
it appeared both in branch.$name.merge *and* in remote.$r.fetch, where
$r = branch.$name.remote.  In other words in the following config file:

  [remote "origin"]
    url = git://git.kernel.org/pub/scm/git/git.git
    fetch = refs/heads/master:refs/remotes/origin/master
  [branch "master"]
    remote = origin
    merge = refs/heads/master
  [branch "pu"]
    remote = origin
    merge = refs/heads/pu

Attempting to run `git pull` while on branch "pu" would always give
the user "Already up-to-date" as git-fetch did not fetch pu and thus
did not mark it for merge in .git/FETCH_HEAD.  The configured merge
would always be ignored and the user would be left scratching her
confused head wondering why merge did not work on "pu" but worked
fine on "master".

If we are using the "default fetch" specification for the current
branch and the current branch has a branch.$name.merge configured
we now union it with the list of refs in remote.$r.fetch.  This
way the above configuration does what the user expects it to do,
which is to fetch only "master" by default but when on "pu" to
fetch both "master" and "pu".

This uncovered some breakage in the test suite where old-style Cogito
branches (.git/branches/$r) did not fetch the branches listed in
.git/config for merging and thus did not actually merge them if the
user tried to use `git pull` on that branch.  Junio and I discussed
it on list and felt that the union approach here makes more sense to
DWIM for the end-user than silently ignoring their configured request
so the test vectors for t5515 have been updated to include for-merge
lines in .git/FETCH_HEAD where they have been configured for-merge
in .git/config.

Since we are now performing a union of the fetch specification and
the merge specification and we cannot allow a branch to be listed
twice (otherwise it comes out twice in .git/FETCH_HEAD) we need to
perform a double loop here over all of the branch.$name.merge lines
and try to set their merge flag if we have already schedule that
branch for fetching by remote.$r.fetch.  If no match is found then
we must add new specifications to fetch the branch but not store it
as no local tracking branch has been designated.

cf818348f1 Report information on branches from remote.h
This adds full parsing for branch.<name> sections and functions to
interpret the results usefully. It incidentally corrects the fetch
configuration information for legacy branches/* files with '#'
characters in the URLs.

b42f69273b Add for_each_remote() function, and extend remote_find_tracking()
The function for_each_remote() does exactly what the name
suggests.

The function remote_find_tracking() was extended to be able to
search remote refs for a given local ref.  The caller sets
either src or dst (but not both) in the refspec parameter, and
remote_find_tracking() will fill in the other and return 0.

Both changes are required for the next step: simplification of
git-branch's --track functionality.

dfd255dd1a Add allocation and freeing functions for struct refs
Instead of open-coding allocation wherever it happens, have a function.
Also, add a function to free a list of refs, which we currently never
actually do.

5d46c9d41f Add handlers for fetch-side configuration of remotes.
These follow the pattern of the push side configuration, but aren't
taken from anywhere else, because git-fetch is still in shell.

5751f49010 Move remote parsing into a library file out of builtin-push.
The new parser is different from the one in builtin-push in two ways:
the default is to use the current branch's remote, if there is one,
before "origin"; and config is used in preference to remotes.
